Answers

Answer:

£100.32

Step-by-step explanation:

An increase of 14% on the original amount (100%) is

£88 × 1.14 = £100.32

Solve V = twh for w.

Answers

Answer:

w = V/lh

Step-by-step explanation:

Given equation:

V = lwh

Solve for w:

V/lh = lwh/lh               Divide both sides by the lh to isolate the wV/lh = w                      Cancel same variablesw = V/lh                      Swap left and right sides

Answer:

V/lh

Step-by-step explanation:

Given,

V = lwh

Here we know

V = volume

l = length

w = width

h = height

Now,

On solving for w

V = lwh

V = l × w × h

V/l = w × h

V/l × h = w

V/lh = w

How can you split 20 into 3 groups

Answers

The answer is 6 per team with 2 left over, as (6 x 3) + 2 = 20

I thought of the largest amount that could be multiplied by 3, but the product would be less or equal to 20, that's how I got 6.

Then to find the left over remaining balls that are given out I subtracted 20-18 = 2.

Answers

Answer:

The given lines are parallel.

Step-by-step explanation:

3y=2-x

y=-1/3x+4

15c=0

c=0/15 or c=0

Step-by-step explanation:

15c + 11 + 6 = 17

subtract 11 from both sides

15c + 6 = 6

subtract 6 from both sides

15c=0

divide both sides by 15

c=0/15

Find the value of each variable in the given figures

Answers

Answer:

q = 22

Step-by-step explanation:

(7q - 46)° + (3q+6)° = 180 (linear pair property)

7q - 46 + 3q + 6 = 180

10q - 40 = 180

10q = 180 + 40

10q = 220

q = 220/10 = 22

m∠ABD = (7q - 46)° = 7(22) - 46 = 154 - 46 = 108°

m∠DBC = (3q + 6)°  = 3(22) + 6 = 66 + 6 = 72°

[tex]\huge\color{Black}\boxed{\colorbox{pink}{Answer♡}}[/tex]

Given ,

[tex]p(x) = ax {}^{3} + 8x {}^{2} + bx + 5 ...(1)[/tex]

Also According to Question ,

on dividing polynomial p(x) by ( x + 2 ) , we obtain ( -25 ) as a remainder.

Therefore , putting the value of x as ( x = -2 )

[tex]p( - 2) = a( - 2) {}^{3} + 8( - 2)^{2} + b( -2) + 5[/tex]

[tex]p( - 2) = - 8a + 32 - 2b + 5 = - 25 \\ = > - 8a - 2b + 37 = - 25 \\ = > - (8a + 2b) = - (25 + 37) \\ cancelling \: negative \: sign \: at \: both \: sides \\ 8a + 2b = 52 \\ dividing \:both \: sides \: by \: 2 \\ 4a + b = 26...(2)[/tex]

also given that..

when the polynomial p(x) is divided by 2x-1 , it gives 0 as the remainder , i.e. , 2x-1 is a root of p(x)

putting value of x = 1/2 in equation (1)

[tex]p( \frac{1}{2} ) = a( \frac{1}{2}) {}^{3} + 8( \frac{1}{2} ) {}^{2} + b( \frac{1}{2} ) + 5 = 0 \\ = > \frac{a}{8} + \frac{8}{4} + \frac{b}{2} + 5 = 0 \\ = >taking \: LCM \\ = > \frac{a + 16 + 4b + 40}{8} = 0 \\ = > \frac{a + 4b + 56}{8} = 0 \\ = > a + 4b = - 56...(3)[/tex]

Now , we have equations (2) and (3) as...

4a + b = 26... (2)

a + 4b = -56... (3)

multiply equation (2) by 4..

16a + 4b = 104...(4)

Solving equations (3) and (4)

a ‎ ‎ ‎ ‎ ‎+ 4b = -56

16a + 4b = 104

-‎ ‎ ‎ ‎ ‎‎ -‎ ‎ ‎ ‎ ‎- ‎ ‎ ‎ ‎ ‎‎ ( bc signs are same )

solving these equations we get,

-15a = -160

a = -160/-15

a = 32/3

putting value of a in (2) , we get...

[tex]4a + b = 23 \\ 4( \frac{32}{3} ) + b = 23 \\ \frac{128}{3} + b = 23 \\ b = 23 - \frac{128}{3} \\ taking \: LCM \\ b = \frac{69 - 128}{3} \\ = > b = \frac{ -59}{3}[/tex]
